//  Upward trend ： Higher highs and higher lows 
//  Downward trend ： Lower highs and lower lows

// 1、 Find the nearest high :  At present 50 Daily maximum price  high1
// 2、 Find the second high point : 50 The day before 50 Daily maximum price  high2
// 3、 Find the nearest low :  At present 50 Daily lowest price  low1
// 4、 Find the second low : 50 The day before 50 Daily lowest price  low2

//  Upward trend ： Average long permutation 
//  Downward trend ： Average short spread 
//  Ideas ：
// 1、 find 3 Average of cycles   Currently used  8,13,21 MA
// 2、 Use the moving average system to judge the trend
